I recently had Source Engineering install their hydraulic fan control in place of the electronic control. It controls the variable fan very smoothly and it is very quiet compared to the original controller. It greatly reduced the fan robbing horsepower from the engine and it feels like I gained 30-40 extra horsepower plus improved fuel economy. It is the best money I have spent on my coach!
Any questions, call Jim at Source Engineering in Veneta, OR (just outside Junction City) phone 541-343-0293
